To all whom it may concern:

Be it known that I, ARTHUR A. KRAEU- TER, a citizen of the UnitedStates, and a resident of South Orange, in the county of Essex and Stateof New Jersey, have invented certain new and useful Improvements inPliers, of which the following is a specification.

The objects of this invention are to provide means for bringing intopositive alinement certain wire-cutting slots in the outer edges of themembers of the pliers; to thus save time in, and avoid the necessity forclose attention to, the manipulation of the pliers in cutting wire; toprovide a construction which 1s simple and convenient to manufacture andwhich is strong, durable and not likely to get out of order, and toobtain other advantages and results which may be brought out in thefollowing description.

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts in the several figures, Figure 1 is aperspective view of a pair of pliers of my improved construction inclosed position, and Fig. 2 is a similar view of the same in openposition; Figs. 3 and 1 are detail cross-sections on line on, Fig. 1 andline 3 Fig. 2, respectively, looking in the direction indicated by thearrows, and illustrating the different positions of a certain stop pin;Fig. 5 is a view from the inside of the fulcrumal portion of the pliersmember having the slot for said stop pin, and Fig. 6 is a section of thesame on line a.

In said drawings, 1 and 2 indicate the two members of the plierspivotally connected as at 3, and having jaws 1, 5 and handles 6, 7,respectively. At said pivotal connection each pliers member has a flatdisk-like portion 8, or 9, which disk-like portions lie flatwisetogether and receive the pivot 3. Edge portions 10, 11 of these disksare exposed, as usual, and provided with transverse slots 12, 13, whichare adapted to come into alinement when the pliers are.

opened as in Fig. 2, and to shear past each other into the staggeredrelation shown in Fig. 1, when the pliers are closed.

When the pliers are to be used as a wire cutter, the slots 12, 13 mustbe brought into alinement as shown in Fig. 2 to receive the wire, and inpliers as heretofore constructed considerable care has been necessary inorder to open the pliers to exactly the right point and hold them sowhile the wire is being inserted. It is to obviate this and to limit theopening of the pliers to exactly that point where the slots will bebrought into alinement, which is the purpose of my present invention.

A central and preferably circular chamber 14 is formed in the inner faceof one of the pliers members as 2, concentric with the pivot hole 16 anddisk like portion 9, and a segmental radial extension 17 of this recess14 provides a chamber whose end walls 18, 19 form stops. A pin 20inserted throu h the other pliers member 1, at a suitab e point of itsdisk-like portion 8, projects at its inner end into the said extensionor chamber 17 and is adapted to engage one end wall thereof as thepliers are opened and thus limit such opening. The location of the partsdescribed is such that the said stop pin limits the opening of thepliers at exactly the right point to bring the wire cutting slots 12, 13into alinement. The stop pin of course never touches the opposite end orwall of its chamber 17, and said stop pin is in the completed pliersfixed in the member 1 either by being driven in tight, as shown, or byany other equivalent means. The shank of said pin is thus fast in thehole in the member 1, while its extremity projects into the recess 17 toserve as a stop. Said extremity is adapted to pass freely through thehole in the member 1, so that the pin can be inserted from the outsideof the pliers. This enables the members of the pliers to be finallyassembled before the stop pin 20 is inserted. Before the said stop pin20 is inserted in the pliers, their members can therefore be openedwider than to bring the wire cutting slots into alinement, and thisenables certain finishing operations which are necessary to be done onthe jaws of the pliers after they are assembled to be performed beforetheir opening is limited.

Having thus described the invention, what I claim as new is:

Inpliers, the combination of members having overlapping portions withcooperating wire-cutting slots at their outer edges, a pivot throughsaid overlapping portions, one of said members having at the inner faceof its said overlapping portion a recess with a closed bottom and theother member having a transverse hole clear through its whereby the pinmay be inserted from the overlapping portion in registration withoutside after the pliers members are assemsaid recess, and a stop pinhaving a shank bled.
